The U.S. took control of a Kaiser pension fund.

Katherine P. Utgoff, executive director of the Pension Benefit Guaranty Corp., which ensures private pensions up to $1,857.95 a month, said the action at ailing Kaiser Steel Corp. would ensure payment of monthly benefits for 176 retirees. The government also is studying the economic health of three other Kaiser retirement plans. PBGC said it became trustee last week for the Kaiser Steel Retirement Plan, which covers 1,000 salaried workers.
